This paper examines if (and how) continuous-time trading renders dynamically-complete a financial market in which the underlying risk process is a Brownian motion and the securities pay dividends that are proportional to geometric Brownian motions. A sufficient condition, that the instantaneous...

Currently, financial economics is unable to predict changes in asset prices with respect to changes in the underlying risk factors, even when an asset's dividend is independent of a given factor. This paper takes steps towards addressing this issue by highlighting a crucial component of wealth...

There is some controversy in the field of household economics regarding the efficiency of household decisions. We make the point that a flexible specification of spousal preferences and the household production technology precludes the possibility of using revealed preference data on household...

We make the point that a flexible specification of spousal preferences and household production technology precludes the possibility of using revealed preference data on household time allocations to determine the manner in which spouses interact. Under strong, but standard, assumptions...

We formulate a model of household behavior in which cooperation is costly and in which these costs vary across households. Some households rationally decide to behave noncooperatively, which in our context is an efficient outcome. An intriguing feature of the model is that, while the welfare of...

Most econometric models of intrahousehold behavior assume that household decisionmaking is efficient, i.e., utility realizations lie on the Pareto frontier. In this paper we investigate this claim by adding a number of participation constraints to the household allocation problem. Short-run...
